Testimonial: "I know how to work on the window. I know how to read the ohm meter and all. Just for the life of me can not find the relay switch. Found the box with the fuses and all are good. Oh well..Not one to be stumped. will get it fixed soon. Thanks for the suggestion anyway..."
Sorry but there is no relay switch , windows controlled by door modules ! Controlled by serial data messaging . (computer) When you push button to open or close window the switch is a low voltage signal to door module , software programmed into module processes inputs an opens or closes the correct window . Maybe the motor is bad ,take door panel off an check power an grounds , or possibly the regulator is bad . regulators break all the time .
